Hi there,

I'm not quite sure what im doing wrong so here is what i need. Simply, i have two radio buttons. I just need to validate if one has been checked, which one. What is the simplest way to do this, or what am i doing wrong?


here is what i've got:

<HTML>
<head>
<script language=&quot;javascript&quot;>

function validate(){

if (!document.form.waiver.checked)
{
window.alert (&quot;You must answer the waiver question.&quot;);
document.form.waiver.focus();
return false;
}

}
</script>
</head>

<body>
<form name=&quot;form&quot; onSubmit=&quot;return validate()&quot;>
<table class=&quot;tiny&quot; border=&quot;0&quot; width=&quot;100&quot; align=&quot;center&quot;>
<tr>
<td width align=&quot;right&quot; valign><input type=&quot;RADIO&quot; name=&quot;waiver&quot; value=&quot;yes&quot; size>Yes</td>
<td width align=&quot;left&quot; valign><input type=&quot;RADIO&quot; name=&quot;waiver&quot; value=&quot;no&quot; size>No</td>
</tr>
</table>

<table class=&quot;tiny&quot; border=&quot;0&quot; cellspacing=&quot;5&quot; cellpadding=&quot;0&quot; width=&quot;90%&quot;>
<tr>
<td width=&quot;&quot; align=&quot;right&quot; valign=&quot;center&quot;>
<dd><input type=&quot;Submit&quot; name=&quot;sub&quot; value=&quot;Submit&quot; align=&quot;right&quot; width=&quot;50&quot; height=&quot;50&quot;></dd>
</td>
<td width=&quot;&quot; align=&quot;left&quot; valign=&quot;center&quot;><div>
<dd><input type=&quot;Reset&quot; name value=&quot;Reset&quot; align=&quot;center&quot; width=&quot;50&quot; height=&quot;50&quot;></dd>
</div></td>
</tr>
</table>
</body>
</html>

Please and Thanks

Checking the value of a radio button doesn't seem to work very well, at least in IE5.5. Try subscript the radio button when using &quot;checked&quot;. For example:
Code: 
if document.form.waiver[0].checked // the 1st radio button
if document.form.waiver[1].checked // the 2nd radio button
